U.S. Trade Representative Robert Lighthizer says he sees trade talks with China entering their final weeks.<br />He made the comments in Tuesday's testimony before the Senate Finance Committee, but he failed to provide a firm deadline on when to end negotiations. <br />He also said he thinks the U.S. should keep the threat of tariffs on China open in order to enforce a trade deal.<br />Lighthizer added that President Trump would not sign a deal unless it was enforceable.<br />This could prove difficult as Beijing wants the threat of tariffs removed. <br />
